The Sapphire Dual-X OC also comes with a faster than average GPU core that is overclocked to 1075MHz, and the card also features a 1GB GDDR5 frame buffer that is factory overclocked to 1600MHz
Mit dem heutigen Tag startet AMD den Verkauf der AMD Radeon HD 7790 - einer neuen Grafikkarte, welche dieses Mal jedoch nicht auf einer Abwandlung eines bereits existierenden Grafikchips aufsetzt. Stattdessen verfügt die Radeon HD 7790 über eine neue GPU mit dem Codenamen Bonaire. Damit will der Hersteller die Leistungslücke zwischen Radeon HD 7770 und HD 7850 schließen und nimmt sich gleichzeitig die GeForce GTX 650 Ti zur Brust. Im heutigen Test vertritt Sapphires HD 7790 Dual-X OC den jüngsten AMD-Spross.
Not too long ago we heard the announcement that AMD were to bring out a new 7000 series card that would fill in a gap in their product line-up to take on NVIDIA's 650Ti GPU. This card is of course the 7790 and goes by the code name "Bonaire". Like we saw way back when the 6790 was released, the 7790 fills the void between the entry level 7770 and the midrange 7850 which is a slightly larger gap than some may think in terms of performance.

Sapphire have given the budget friendly HD 7770 the Vapor-X treatment and increased the clocks, but does it make a difference?
